The chemical composition of PM_(2.5) at two sites in Lebanon,a country in the East Mediterranean-Middle East region,is investigated in the spring and summer *** average PM_(2.5) concentrations were of(29±16)μg/m 3 for Beirut urban site and(32±14)μg/m 3 for Beirut suburban *** study showed that the geographic location of the East Mediterranean region,such as its proximity to the Mediterranean Sea and the dust storm intrusion are a significant contributor to the high PM levels from natural sources,which cannot be mitigated,rendering the PM_(2.5) WHO annual Air Quality guideline unattainable due to high natural background,which also applies to the entire Middle East *** and Eastern Europe are the dominant origin of air masses throughout our sampling days,suggesting the long-range transport as an important potential contributor to the high observed concentrations of V,Ni,and sulfate in this region most probably in other East Mediterranean countries than Lebanon *** local sources determined through the chemical speciation including organics are road transport,resuspension of dust and diesel private generators.A health risk assessment of airborne metals was performed and the carcinogenic risk for all the metals exceeded by 42(adults)and 14(children)times the acceptable risk level(10^(-6))at both *** was the predominant carcinogenic metal,emphasizing the need to replace energy production with cleaner energy on a regional level and highlighting the severe impact of air pollution on the health of inhabitants in this region’s main cities.

摘要基于肌酐为方程式来评价肾小球滤过率(GFR)越来越多地应用于放射学实践及与对比剂诱发急性肾损伤(CIAKI)研究中,在指南与对比剂教科书中其被用于CIAKI与肾源性系统纤维化的高危人群的识别。基于血清胱抑素C的GFR计算公式也受到更多的关注。GFR方程式的应用要求肌酐与血清胱抑素C化验进行校正,避免过高或过低地估

Fig (Ficus carica Linn (Moraceae)) is a deciduous tree that grows in tropical and subtropical zones [1]. Ficus carica has a broad spectrum of pharmacological activity and is widely used in traditional medicine. Research has found its use in more than 40 areas. Some of these are gastrointestinal, endocrine, respiratory, reproductive system disorders [2]. The fig seed oil contains alpha-linolenic acid (ALA), which is highly beta-sitosterol and herbal omega [3]. It can be used as a supplement in the treatment of diseases such as cardiovascular disorders, gastrointestinal disorders, and diabetes. Fig seed oil can be a good choice for skin hydration when used externally. In our study, the fig seed oil was analyzed by gas and liquid chromatography. In this study where linoleic acid (C18:2) and linolenic acid (C20:0) ratios found in fig seed oil composition were evaluated, the health benefits of two fatty acids were discussed based on the literature.

Chronic Spontaneous Urticaria (CSU) is a chronic disease with significant negative impact on quality of life of patients. The direct and indirect costs of the disease can be substantial both for the health care system and society. The aim of this research is to estimate the cost of mild, moderate and severe CSU in Turkey and to forecast the cost of the disease from the payer (Social Security Institution—SSI) perspective. Expert opinions with Delphi technique were used in order to determine the cost items and their frequency. A questionnaire was designed to outline resources used in the out-patient, inpatient and emergency care episodes and was answered by dermatologists followed by a consensus meeting. Unit costs were calculated from the price list of the SSI. The annual total cost of treating the disease to the SSI was estimated as 262,111,978TL (94,417,870€) comprising 0.06% of the total healthcare budget in 2013. Since there is limited information about the cost of CSU in Turkey, the methodology and results of this study are unique and very important.
